About the Role
Collections & Treasury is building a new collections product and the financial backbone for other business areas. This includes building infrastructure for on-demand vIBANs, designing customer-facing APIs for collections, and handling real-world collections challenges across Africa. This role requires a Senior / Lead Engineer with financial systems experience to build a robust and scalable Collections & Treasury foundation.
Responsibilities
- Own key architecture and implementation decisions for the collections & treasury foundation
- Lead design work (RFCs, diagrams, API and system specs) to align on solutions before building
- Partner with PMs and stakeholders to translate business intent into technically sound requirements
- Design and build customer-facing and internal APIs to support collections and payment strategies
- Build reliable infrastructure for vIBAN provisioning and collections orchestration
- Drive engineering quality across API standards, testing strategy, code review bar, and maintainability
- Manage delivery by breaking down complex work, sequencing milestones, and keeping projects moving end to end
- Make pragmatic trade-offs: move fast where we can, protect correctness where we must (especially in financial systems)
Requirements
- Have worked with Go in a production environment
- Understand how to translate business intent into technical requirements and clean system boundaries
- Understand what “good” looks like in financial-grade systems, including correctness, reliability, auditability, and operational readiness
- Familiar with design principles that drive maintainability (single responsibility, separation of concerns, etc.)
- Knowledge of API fundamentals, including consistency, versioning, backward compatibility, and developer experience
- Requirement gathering: quiz PMs, challenge stakeholders, and push on solutions that do not make sense
- Do not accept proposals from non-technical people at face value; turn business intent into something technically sound
- Design-first approach: draw diagrams, write RFCs, explore hypotheses, and visualize systems at a high level
- Avoid freestyling into implementation without alignment
- Care about good API design and reusability
- Write unit-testable code and advocate for quality during code reviews
- Understand that in financial systems, “it works” is not the bar
- Disciplined execution: own complex projects end to end
- Avoid excessive context switching and push back when too many parallel things risk delaying delivery
- Care about finishing work properly, not just “mostly done”
- Proven delivery of complex backend or distributed systems in a production environment
- Experience owning systems end to end, from design to build to ship to operate to iterate
- Experience working closely with PMs and stakeholders to shape solutions, not just implement them
- Experience making pragmatic trade-offs in startup environments, balancing speed, correctness, and scope
- Calm, decisive, and effective in ambiguous environments
- Collaborative by default, aligns early, communicates clearly, and brings others along
- High ownership with high standards, accountable for outcomes, not just output
- Pragmatic, not dogmatic, knows where we can compromise to move fast and where we absolutely should not
